Abstract

We sought to determine the proportion of rotavirus ( RV) infections among children with severe diarrhea in Bangalore, India, and to determine the role of neonatal infection with the asymptomatic RV strain I321 in protection against subsequent RV diarrhea. At 2 major hospitals, there was a >42% decrease in diarrhea-specific admissions during the study period. At 6 hospitals, asymptomatic infections were found in 25%-50% of neonates, when screening was performed randomly, and in >58% of neonates, when screening was performed daily, with the majority of infections occurring within the first 7 days of life. All the RVs found in asymptomatic neonates were strain I321. A 24-month follow-up of a cohort of 44 children who had been neonatally infected with strain I321 and 28 children who had not (control group) revealed comparable rates of RV detection but a marked decrease in the number of RV diarrhea episodes in the strain I321-infected group (2.3%), compared with the control group (39.3%) (P < .0001). This preliminary study suggests a possible association between neonatal infection with strain I321 and protection against subsequent RV illness.
